How to auto caption generator
- 1
Upload your video
Drop your video file into CentClip - no sign-up or credit card needed. Your first 5 minutes of captioning are free, so you can check transcription accuracy on your actual footage before spending anything. Most common formats including MP4 and MOV are accepted.

Review and correct auto-generated captions
CentClip generates a time-synced caption track automatically using speech recognition trained across 50+ languages. The editor shows each segment next to its timestamp, so you can fix any misspellings, proper nouns, or technical terms before exporting - a step that typically takes a couple of minutes for a polished result.

Export captions in the format you need
Download a finished MP4 with captions burned permanently into the picture, or grab a separate SRT or VTT file to upload directly to YouTube, Vimeo, TikTok, or any other platform. A plain text transcript without timecodes is also available if you need the words alone for a blog post or summary.
Why choose CentClip?
The generator does the timing work - you only fix mistakes
Manual captioning requires you to listen, type, and align every line to the right second - a 10-minute video can take 90 minutes to caption by hand. CentClip auto-generates the full caption track with timestamps already set, so you spend a few minutes reviewing rather than hours transcribing. That time difference matters when you have a backlog of footage or a same-day publishing deadline.
No subscription means no wasted spend on slow months
Subscription captioning tools charge the same flat fee whether you caption 20 videos that month or zero. CentClip runs on credits: a 10-minute video costs 50 cents, a 60-minute webinar costs $3.00, and any credits you don't use roll forward indefinitely. If you have a busy quarter followed by a quiet one, you pay exactly what you use - nothing more.
Captions that reach viewers regardless of how they watch
SRT and VTT files only display captions when the viewer's player has subtitles turned on - a setting most people never touch. Burned-in captions are embedded into every frame of the MP4 itself, so they appear on every platform, every device, and every player automatically. For content shared to social feeds where video autoplays without sound, burned-in captions are the only approach guaranteed to be seen.
